Electromagnetic Environment - Guidance
The 3M Bair Hugger Patient Adjustable Warming Unit, Model 875 uses RF
energy only for its internal function. Therefore, its RF emissions are very low
and are not likely to cause any interference in nearby electronic equipment.
The 3M Bair Hugger Patient Adjustable Warming Unit, Model 875 is suitable
for use in all establishments, including domestic establishments and those
directly connected to the public low-voltage power supply network that
supplies buildings used for domestic purposes.
